We've just spotted a familiar friend at Intel's Innovation Future Showcase in London -- its Haswell-powered North Cape laptop / tablet hybrid. As a quick reminder, alongside that fourth-generation Intel Core processor there's a 13-inch 1080p display that detaches from the keyboard, and now we've been given a few important updates on the reference device, battery performance on Haswell and how Intel's reference design will transfer between tablet and Ultrabook mode. All that and more after the break.
